针对大柳行金矿⑧-1号急倾斜极薄矿体开采难度大、回采效率低、作业安全性差的难题,使用传统的工程类比法、理论分析法优选采矿方法时,诸多定性指标难以准确评价.基于未确知测度理论初选出上向水平分层干式充填采矿法等5种适合大柳行金矿矿体的采矿方法,通过确定科学合理的评价指标体系,采用采场生产能力等6种定量指标与机械化程度等3种定性指标并重的方式,优选出上向水平分层干式充填采矿法作为指导该矿实际生产的采矿方法.经生产实践证明,由未确知测度理论优选出的上向水平分层干式充填采矿法能够很好地适应大柳行金矿的实际情况,并取得了良好的应用效果.
Many uncertain indexes are difficult to assess when conventional engineering geological analogic comparison method and theory analysis method are used to opt for better mining methods,because of mining difficulty,low recovery efficiency and poor operation safety problems mining the steeply inclined and extremely thin No.⑧-1 orebody in Daliuhang Gold Mine.This paper selects five mining methods suitable for the mine such as the upward sub-level dry filling mining method and based on reasonable evaluation index system,six quantitative evaluation indexes like production capacity and three qualitative evaluation indexes including the level of mechanization are combined to select the first-rank method.Production practice shows that the upward sub-level dry filling mining method selected by the uncertain measurement theory can be well suited to the actual situations of Daliuhang Gold Mine.And the application achieves satisfactory results.
